Pescatarian Diet
A pescatarian diet usually avoids meat and poultry while including fish and seafood, alongside a wide range of plant foods. Some people also include eggs and dairy.
This full Space to Breathe Therapy Nutrition Library guide explains what pescatarian eating can look like and how to build a balanced pattern rather than simply replacing meat with fish.
The guide covers protein, omega-3 fats, iron, vitamin B12, iodine, vitamin D and calcium, with practical information about oily fish, white fish, shellfish and tinned fish. It also discusses current UK considerations around mercury, pregnancy and fish choices.
Inside you will find realistic meal ideas, a shopping framework, budget-friendly options, eating-out guidance, convenience foods and ways to move gradually toward pescatarian eating.
There are dedicated sections for ARFID, autism and sensory differences, fish and shellfish allergies, eating disorders and restrictive eating, pregnancy and breastfeeding, children, older adults and people with low appetite.
The guide finishes with common myths, a personal nutrition check-in, guidance on when professional support may be useful, and a supportive message from Space to Breathe Therapy.
The aim is not to tell you that pescatarian eating is right or wrong. It is to provide balanced information so you can consider whether it is nourishing, safe, realistic and sustainable for you.
